CREATING A FUTURE PROOF PATH FOR US BROADCASTERS NEXTGEN TELEVISION
ATSC3.0 will bring around a real range of very positive changes that revolutionize the way terrestrial TV works. The new standard completely modernizes over-the-air broadcasting, bringing more interactive and feature rich content and allowing viewers to access services on mobile devices. In short, it brings the over-the-air viewing experience much more in line with the needs of a modern audience and allows it to truly compete with the growing OTT market.
LOOKING AHEAD However, NEXTGEN TV goes beyond improving viewer experiences, and, deployed correctly, can give broadcasters the foundation future developments.
RFS looks at how ATSC3.0 will change how over-the-air TV works at a fundamental level and the opportunities this presents for US broadcasters. NEXTGEN TV infrastructure will create a unique style of network for broadcasters. The standard requires a hybrid broadcast and IP-based delivery system, meaning it can carry internet content and services alongside the traditional over-the-air broadcast signal. This is the first network of its kind and with the demand for IP based services skyrocketing, by moving to ATSC3.0 standards, broadcasters will inadvertently create a delivery network that has potential revenue streams beyond its primary purpose. In fact, research from WideOrbit reported 69.9% of broadcasters saw meeting ATSC3.0 standards as a potential revenue driver. So, how do broadcasters go about making this a reality and what do they stand to gain?

THE RISE OF SFN In order to build a network that will meet these new standards, broadcasting infrastructure will need to undergo a major transformation. Single Frequency Networks (SFN) are a critical part of realizing the potential of NEXTGEN TV and so broadcasters must now look at the best way to go about building this new style of broadcasting network. SFNs offer a huge range of advantages for broadcasters; better coverage, lower power usage, higher reliability, and they are capable of delivering the hybrid broadcast and IP-based system defined by ATSC3.0. They are ideal for the geotargeted and the enriched content that is part and parcel of what NEXTGEN TV will look like for consumers and creating the additional revenue opportunities broadcasters are set to benefit from as part of the upgrade.
GETTING THE INFRASTRUCTURE RIGHT One of the big challenges on the way to NEXTGEN TV is infrastructure. Broadcasters need to put in place networks that are up to meeting ATSC3.0 standards not just in principle but in practicality. When designing the networks, simulation of how the broadcasting set up will overcome physical challenges is vital. Broadcasters must work with their infrastructure providers to design radiation patterns that meet the needs of their region without coverage gaps, and without interference or disruption. Additionally, having gone through an intense period of investment, broadcasters have even greater pressure to ensure that the upfront costs when it comes to NEXTGEN TV equipment, are protected and look to install equipment that will see them through not only this phase of the
evolution of broadcasting, but continue to serve them over the next decade. Part of this must be to focus on the needs broadcasters have today and tomorrow, but an eye must be firmly fixed on the convergence of the telecoms and broadcasting industries. As the two areas see increasing amounts of overlap, understanding the trajectory for this convergence and how they, as a broadcaster, will navigate this is critical.
NOT JUST A STEPPINGSTONE, IT’S THE FOUNDATION OF 5G BROADCAST Looking to the future, it is understandable to ask why not skip ahead to 5G broadcast? We know it’s coming, and it is the next step for many other regions. However, in reality, the scale and geography of the US make 5G broadcasting an impossible proposition over the next few years. Operators do not have the capacity to scale up 5G networks quickly enough to deliver broadcasting and it isn’t their priority to. However, rather than lagging behind, this actually builds a firmer foundation for the US broadcasting market as 5G becomes part and parcel of the delivery of television. The combination of broadcast and IP-based delivery that broadcasters are building to meet ATSC3.0 standards is set to build a comprehensive and robust failover system. Broadcasters will, by coincidence, have access to an enviable network for the delivery of IP-based content that can be both used to support broadcasting or monetized to those looking for capacity to introduce another revenue stream. Ultimately, the ATSC3.0 standard will give the US market a truly futureproof foundation for content delivery by having to use this interim stepping-stone and at RFS we are at the forefront of developing solutions to support this.

The narrowband input corresponds to the bandpass resonant frequency, whereas the wideband input can be any other channels in the applicable UHF band. Modules are connected together to provide a multichannel combiner. The order (number of poles) of the filters will determine the channel spacing required for given channels, and also the mask, if any that may be provided. • • • •

DELIVERING FUTURE-READY SOLUTIONS FOR A S U C C E S S F U L B R OA D C A S T E VO L U T I O N RFS is committed to developing cutting-edge, cost-effective broadcast solutions designed to outlast other systems while never compromising on performance. We anticipate the evolving technology needs of our partners creating greater connectivity within the markets we serve and representing one simple force – the design, manufacture and deployment of RF technology, systems and services. RFS has advanced RF simulation and modeling to the point where antennas can be fully built using design simulation software so that the manufactured product will not require any additional tuning.
Pioneering significant advancements for RF broadcast antennas, filters and combiners has greatly reduced lead time, increasing the factory’s capacity to produce more antennas in a shorter time.
RFS’ USA-based state-of-theart manufacturing facility with more than 350,000 sq. ft. is located in Meriden, CT. It contains near and far field test ranges and abundant covered storage areas.
From design to manufacture, ISO 9001 and ISO 14001 certification standards and LEAN manufacturing methods encompass all aspects of RFS’ business worldwide.
ON TOP OF THE WORLD RFS spent several years working closely with The Durst Organization, Myat and individual broadcasters on UHF and VHF antenna installations for One WTC – the tallest building in the Western Hemisphere – delivering terrestrial television services to the entire NYC coverage area. The new infrastructure atop the iconic venue incorporates RFS’ Variable Polarization Technology (VPT), providing broadcasters with the flexibility to define their own polarization ratio. The official start of relocation of live broadcasting to One World Trade Center (One WTC) in New York City began on 23 June 2017. WNJU CH36 is the first television channel to transition broadcast operations to the new future-proof antenna deployment at One WTC, which is comprised of RFS’ UHF PEP40E antenna, combiner and RF switch frame.

READY FOR NOW & WHAT COMES NEXT
Broadcast Solutions
RFS’s 2022 project at the One World Trade Centre site, builds on the 2017 repack deployment, which baked in ATSC 3.0-ready capabilities. This latest project was driven by several broadcast stakeholders, including The Durst Organization, responsible for the site, all looking to lead the way on broadcast innovation. It will use RFS equipment to
transmit an ATSC 3.0 signal over the complete metropolitan New York area by the end of 2022, the first high power ATSC3.0 signal for New York. This will enable broadcasters to take advantage of features, including HDR, interactivity, and transmission to hand-held devices. In this deployment, an extra channel is being added to the existing RFS
main and auxiliary antenna and combiner systems. In addition to the combiner add-on equipment, the system incorporates 12 pole mask filter systems for both main and reserve operation that are combined with an RF switching system to provide high levels of redundancy and flexibility.
